Xoom screen dim on the bottom edge

I searched around the forums and did not see anything else posted about this. I just bought the WiFi only Xoom and am very happy with it, except for the fact that the bottom edge of my screen is darker and dimmer.
To clarify a little bit, I mean the edge of the screen thats next to the ports on the bottom of the Xoom. Normally its impossible to notice since I usually hold my xoom in landscape and there is the black bar at the bottom. If I open a pdf file or ebook, and then view it in portrait mode, I notice a darkening of the screen along this edge. It kind of looks like a shadow or a very slight black blur. The darkness is not that exaggerated but once I noticed it, I could not stop looking at it when reading.
Now I normally go on a witch hunt for problems with new devices when I first get them. The more I pay for them, the harder I look. I thought at first I might be doing this with the xoom and kind of blowing this out of proportion, but last night I was showing it off to a friend and he noticed it before I even mentioned it.
Does anyone else notice the darkness along the bottom, or do I just have a defective panel? Its easiest to see if you put your brightness around 80% and then display something that has lots of white, like a pdf or ebook, and then hold it in portrait mode.
I will post pics of it when I get home tonight.

i've noticed on all the xooms i've looked at too, including the one i bought. someone once replied that it was defective, but i think it's actually how it's made.
most people's eyes may not be sensitive enough to notice this i suppose.

I hope this is not the case. This might be a deal breaker for me since I need a device that I can read on a lot.
Can anyone else verify this?

Mines not like that. I'm using the Verizon one. I use it in portrait often.

i just exchanged my defective one (had wake issues) for a new one and guess what - dim bottom too.
that makes 8 xooms i've looked at that have the dim bottom. it's only noticable on white/light bg and if you don't have your menu bar covering it.

i picked up the wifi xoom yesterday and noticed it when togglieing the bottom right corner setting button (battery indicator). When looking at this the entire right portion of the screen dims. Other than that, it is not noticeable.

This is a purposeful UI effect (what you are talking about, not the OP).
For the OP, I looked at my Xoom diff brightness levels, angles, orientations, etc, cannot see any dimming. 3G model. Not very helpful, I know.

also, if you look at the top of the screen (landscape mode) at an angle you can see the light source. the lighting just isn't even. i'm positive that if i look at anyone's xoom i'll see it since the back lighting is made the same on all... unless they switched mfg's in production like the evo4g's did.

Well thats a real bummer. I think I might just hold onto mine for a while and maybe try and do a warranty replacement later in the year if they fix this issue.
Did you notice any 3g models having the dim bottom, madsquabbles? Or for that matter, has anyone noticed this on the 3g model?

I first noticed it on the 3G. thats when I posted my first question.

Weird screen issue, confirmed on two so far.

I don't know if these if happening on all our s2's.
basically, I noticed brightness goes down when displaying a lot of whites. e.g. google vs the whites in a page with more darker areas. (i don't think it's my eyes.)
I've never noticed this on my hd2, or any other phones.
when displaying google's in the browser, the white is not impressive at all.
another test i did was with an image I created (attached), half black half white. open in gallery and slide it so more black shows, or more white shows. The whole screen changes brightness!
My friend's S2 does the same.
can anyone confirm?

That's actually a power-saving feature you can turn off.
Go into Settings -> Display -> Scroll down and untick 'Auto adjust screen power'.

Its not.
Its definitely there irrespective of display settings.
Basically even when you are not moving picture, have a look near the border.
There is definite grey banding near the border. It kinda looks like white is bleeding into the black.
And its there on every SGS2, every single one. It can be hardware or software issue.
@OP. you are definitely not alone. I was actually having talk with my friends in UK. 6 of us now have SGS2. 2 are from O2, 3 from P4U and 1 from Handtec and mine is from Clove.
All are experiencing same thing. Its definitely not your eyes.
@others. Its not a glaring issue. You wont notice i t unless there is extreme contrast images on screen like this one. My dad still couldnt notice it when I was showing it to him. But its still there. Will upload video, but its hard to pick on video as well.

It's an option in the Display settings - auto adjust screen brightness after analysing image or something similar.
Samsung thing, I think, since my Omnia 7 with Windows Phone did exactly the same thing. It's trying to save you power and completely normal.

Thanks very much guys, I think I can accept it if it's all built like that. With that option off it really helped! (I feel a lil retarded now). But for some reason that test image I made still has that dimming effect (double tap it in the gallery, this instant change makes it obvious), but maybe that's normal, not fussed. (normal web browsing is perfect)
And no I didn't exchange any phones. Mine does have a dead pixel tho. Can anyone check their screens for dead pixels for me? I know someone had blue lines and stuff on their units, that's a bit drastic. I'm just wondering how many actually have say 1 dead pixel, so I have a better picture before I actually exchange mine or something.

asefsef said:
Yea, I've already got that turned off including power saving mode (mentioned in first post).

Nah, no dead pixels or other screen issues here. If you have dead pixel, i would return it.
Here is the video, its not clear as camera limitations dont really show it properly, but at 720P you can see it for fraction of second, that is not the lens glare but screen turning grey right above the white border.
http://www.youtube.com/watch?v=zGr7xJ1JIjU
around 0:15-0-18 in that video.

As mentioned, its a power saving feature as AMOLED screens don't like whites as they drain power, they prefer blacks. So reducing the brightness helps to save battery.

I can see it grey in the video, almost like that gingerbread scroll limit effect. very hard to see in the video though, would have just said it was the camera.
Yea I'm considering returning. In my other post, I mentioned how Handtec got back to me. In short, not fault since only 1 pixel, but told me I can exchange/return within 7 days. But, they said since it's not a fault, I'll have to pay shipping both ways. (£28 per way, ouch)
Does that sound right??

Just a thought, could not the grey area when moving a black/white border area simply be the screen pixels taking a few milliseconds to go from completely dim, to grey, then to completely white, ie just a response time, albeit a bit slower than what I would have guessed?
On my SGS, going into a completely black app drawer with bright icons and moving around, it also has a very slight dragging effect on some white/black constrasting areas?

Display problem/yellowish left side

Just got my new SGS2 3 days ago, really liking it but stumbled into a screen problem and would like to know if it's just me/it's normal/I need to change a setting to fix the problem.
Just like the title says, the left side (about 1/3) of my screen changes the colour of the image to a more yellowish tint. This seems to happen just when the brightness is quite low, and tends to disappear when close to 100%.
It is rather subtle, but can be seen where there's white text on a darker background (white characters become darker the closer they are to the left border), or when looking at an uniform colour.
I created this test page to make the problem more apparent: http://fiddle.jshell.net/qFxsC/1/show/
When visiting it on the S2 browser and setting browser brightness to around 20%, it becomes quite visible.
Anybody else with the same problem?
EDIT:
We still DO NOT have pictures of a phone WITHOUT the problem described above!
If you believe your SGS2 has a perfect screen, please post pics of the notification area taken in the dark at both 0-20% brightness and 100% brightness!
UPDATE
Various websites have started to talk about this problem, linking to this thread:
- http://mobile.engadget.com/2011/05/30/is-your-galaxy-s-iis-display-yellow-on-the-left/
- http://pocketnow.com/android/samsung-galaxy-s-ii-screen-problems-trouble-in-paradise

- http://gsmarena.com/samsung_galaxy_...y_uneven_brightness_yellow_tint-news-2719.php
I have just sent an email to GSMarena asking if they could check the unit they reviewed to see if it has the same problem. Of all the phone reviews I have seen, theirs seems to be the most focused on image quality, I'm sure that if their unit doesn't have this problem, they would be able to take clear shots of a flawless screen.
EDIT:
GSMarena took screens of their unit using the above test link, and while so far I believe theirs is the best looking display that we have seen so far, it *STILL* has the problem.
I am going to link this thread to samsung UK next, in the hopes they will give an official answer acknowledging the problem.
EDIT:
latest firmwares seem to fix this problem or at least make it much less noticeable.

Take it straight back and swap it. Seems to be a growing amount of people on here, including myself, with various dodgy screen issues.
B

The screen doesn't look perfect if you look at a uniform color on the whole screen + low brightness, but... well I don't tend to use it much for that. Could be a limitation in OLED production-technology getting all the pixels to have exactly the same brightness/color etc.
edit:
To answer directly to the question here, no I don't have a yellowish left side. It's just not completely uniform across the whole screen.

I've got this same thing. I first noticed it when using Estrongs file explorer. I always have my screen turned down to 0% to save battery, but didn't notice this anywhere else yet (at least I didn't think about it).
Your posted image does show it clear.
What to do? Could you others comment whether you've seen this? Go to the OP's posted link and set your brightness down to 0%.

I tried to mess around with settings such as auto adjust screen power etc, but the only thing that seems to fix it is crank up the brightness.
We obviously can't keep it anywhere close to 100% tho, this phone sucks battery down quickly already at 0%!
Another thing you can do to check if you have this screen problem is call *#*#0*#*#*
This will make the phone go in the diagnostic program, and if you try the white diagnostic, you can somewhat see the problem, although not quite as clearly as in the test web page I posted above.
I'm considering to return the phone, as it doesn't seem to be getting better, despite having read that some screen problems might go away after a few days.

Mine is exactly the same. It's noticeable at the lowest brightness setting, however if I increase the brightness even slightly it pretty much disappears for general use. It's still there but not really enough to bother me.
On the OP's link I changed the brightness through several settings and at certain brightness levels the whole screen gets a yellow tint. Not necessarily related to the left side of the screen having a yellow tint, apart from I guess a lack of brightness of the blue subpixels relative to the red and green.
I'm not sure if I'm imagining it but I think it has improved slightly on mine over the past week. However if it gets any worse I think a warranty claim will be in order.

Hhrrmm, I'm in a catch-22 here. There's generally a grace period for any manufacturing errors like this where you can quickly get a replacement just by returning it to the vendor. Problem is, my vendor won't be getting any new units in for another two weeks.

I don't see it clearly on the link he posted.
But i do see it in the notification screen. The grey area is slightly darker/yellow tint on the left site. Even when i put it on maximum brightness you could see it. Especially when you first concentrate your eyes on the right side for 5 seconds and than on the left side.
I do seem to notice it on the notification grey slider where your finger is on when you pull it down, on the left side the grey is a little bit "darker" than on the right side of mt finger.
I tend to think I can also see it on the keyboard, whereas the Q has different grey than P on the opposite of the screen...
Anybody could check this out on their phone??
Thanks in advance!

As time goes by, it feels like my problem is getting worse, although it may only be due to me being aware of it.
Also began noticing it in the pull-down message field. Now I see it against white backgrounds as well, almost like a faint green-grey shadow.
I've contacted my vendor and requested an RMA and replacement. They're sending me a shipping slip to send it to them "for control" then they'll contact me on my options from there. Can only hope they see it as clearly as I do and that they send me a new phone as a replacement rather than repair/refurb crap.
Think this is the last time I buy electronics online. I saved 20% off retail on this one, but having the option to do a walk-in replacement at a brick-n-mortar store would have been worth the higher price. <sigh>

I've got the same thing aswell, a slightly yellow/brown-tinted shade towards the left side of the display. Also visible for example in the market menues, the white areas seem to be very slightly darker towards the left side.
Not sure I am bothered about it enough to return it, doesn't bother me unless I specifically look for it. Also it really is very slight.

If everybody has it, no problem for me.
But if the majority does not have it, I would like to have one without it. Do you think Samsung knows abouth it?
When you have a full grey pictuere or just the notification screen and you go into a perfect dark room. Can you also see, some white vertical en horizontal lines? Looks like hardware where the screen is build on?

Here is a photo I took of my screen with a grey background (see below - click on it to enlarge).
For me, its visibility seems to vary depending on the ambient light, but I'm definitely seeing more effects of it now.
Really hope I'm able to get a good replacement. Am reading quite a bit about this, banding, lines and dead/lit pixels.

so do you think it's a hardware issue, or maybe it will be gone??

The lines you mention are present both on my SGS and my SGS2. It seems to be patterns in the actual OLED pixels, and the patterns and lines are static even when you move pictures. Mostly visible on lower display brightness settings. I've gotten used to them and they don't bother me, and since I have the same thing on two SAMOLED-phones I'd chalk that one up to "just the way it is" aswell. Using anything over 50% brightness has them mostly fade into the display light so only really visible on the lowest brightness settings.

This what you mean?
My Samsung focus and Cowon s9 (which I don't even think has a samsung oled screen) have that as well on the lowest brightness, I think its inherent to the tech.

Ah ok thank you!
On a grey pick with full birghtness I can see them too.
On the post 2 post above yours(quist his post) you can see the lines, but now they are not white, but darker, can you confirm you see them and this is what you mean?
Do you also have the yellowish tint on the left side?

For both the SGS and SGS2, the dark lines are there for my devices aswell. They can seem a bit "grainy", and don't seem like perfectly defined lines, though they generally are always straight horizontal or vertical lines. I also have the Xperia Arc at hand, and if you look at a grey-ish image on either the SGS/SGS2, or the Xperia Arc (LCD), the Arc generally has a very smooth grey image, while the SGS/SGS2 has almost like a fine overlay of subtle lines or grids, generally darker in color than the image displayed, though not clearly defined and not completely symmetrical across the display.
Doesn't seem symmetrical enough to be a grid fo the digitizer layer or smtn like that, but definitely a pattern in the display itself. I still pick an AMOLED screen anytime of the day, the Arc display, while more uniform and "blemish"-free in this regard, still has that LCD backlight bleed-through which for me makes the display alot more tiring for the eyes.
Also my SGS2 has a very subtle tint towards yellow when viewing some of the grey test-images some people have posted. Never noticed it on my SGS1, so either I didn't look well enough, or it might be either hardware-related (something causing the pixels on the left side to perhaps not get the same amount of control voltage/whatever for the pixels, thus causing less blue/more yellowish color), or software. Either way, it is way too subtle for me to care at all, maybe this is even according to spec for the SAMOLED+ and some use will even the pixels out, not sure if anyone has some inside knowledge about the SAMOLED screens.

I am definitely seeing this problem getting worse, now it is getting rather obvious as long as phone is lit by artificial light or in the dark, while sunlight seems to make it really hard to spot, even if not direct.
I've been given advice from samsung call center to bring to phone to the closest assistance point, which I'm going to do tomorrow - hope to be able to report back that it is a known problem and they will change my unit.

I hate to make an iPhone reference here, since I'm *not* a fanboy, but Engadget reported when the IP4 was released that yellow spots and banding were due to glues that had not completely dissolved/disappeared and were part of the bonding process of the screen:
http://www.engadget.com/2010/06/24/iphone-4s-yellow-spot-issue-goes-away-with-a-bit-of-time/
Now - the picture above showing a completely yellow left-side display - that looks 100% abnormal and I'd RUN back to the store to swap it out. I don't think that's glue related.
Download an app from the Market called "Dead Pixel Test" and run it with the white setting to see what it looks like. Is it still yellow?

Have this same issue. Noticed it right away unfortunately. It will always bother me if I deal with it.

SAMOLED+ Pixel Response Time and Touch Screen Discussion & My Review of These Parts.

SAMOLED+ Pixel Response Time and Touch Screen Discussion & My Review of These Parts.
Hey all, I wanted to start a thread to have a discussion about these two things that are my only disappointments in this phone.
Let me start by saying I think this phone is awesome, and yes I feel there are a few other faults on the phone (lockscreen delay when running off the battery due to the CPU taking a second to kick in, weak GPS/wifi signal sometimes, heavy banding on gradients etc) But those are software issues and I know in the near future Samsung/Devs will sort this out.
But I had some big complaints that aren't (still I hope not) software issues. Firstly;
- Response Time.
By this I mean when you buy a new monitor and the response time is listed as 4ms or whatever. This is the time the pixel takes to make a full change. A slow response time will cause ghosting. And that's exactly a issue that the Samsung Galaxy SII faces. Ghosting.
I've gone through 4 replacement SII's for various reasons, and on all of them they ghosted. So it's not just my phone. Samsung bizarrely states the response time is 0.001ms which would be there would be no ghosting at all. However there is, quite a bit actually, by my testing the screen is actually around 6-8ms.
I want to see if anyone else notices it. I know there's been a couple of threads on this but I want to see if the majority of people notice this. Here's how to test, go onto white page with black text on, and then scroll down the page at a moderate pace, not to fast not too slow, try it at different speeds as well just in case you don't get it right.
The easiest way I find to do this is use the inbuilt stock news app, load up any story and it'll give you a long white page with black text you can scroll through. As you may notice if you got a decent set of eyes on you, the text will leave a trail. Also known as ghosting. To me, I find this absolutely unacceptable on such high end device.
- Colour
Also, as it's been widely reported and has been noticeable on all my GSII's, the colour temperature is very 'cool', nowhere near the perfect 6500k. As a result, white's look very blue. This is fine and you hardly notice it on it's own, however when I'm using the device at my PC, which I use on a 32" IPS panel TV I professionally calibrated, the whites on the GSII look more blue than the ocean! Technically this is a software problem and can easily be sorted when custom roms come along but jeez, this is some bad stock colour calibration.
Also when you tilt the display, the viewing angles are generally very good, however tilting the display by pretty much any angle adds an extra blue tint to the screen on an already blueish screen.
I'm an absolutely screen quality perfectionist so these points really get to me. Especially considering this is such a high end device.
Overall I'd give the display a 6.5/10.
After the colour temperature has been sorted, I'll give it a 7.5/10.
If the ghosting can get minimized somehow even slightly through software on top of that, I'd give it an 8.5/10.
Secondly;
- Touch Screen
Now we all know about the movement deadzone/threshold on the touch screen which is massively annoying, but hopefully that'll get fixed in the near future. But What I'm going to complain about is the low sensitivity of the touch screen is the best way I can describe it.
On my HTC Desire, I can tap the screen ridiculously lightly and quick, and the device will register the input, absolutely no questions asked. Absolutely brilliant.
However on the GSII the sensitivity seems to be a lot lower, I can tap the screen lightly and quickly and the screen won't register the touch at all. This is pretty damn annoying as sometimes I just tap the screen lightly normally and I have to retap things. Not very often but still. I wish the device was as sensitive as the HTC Desire.
In it's current state I'd give the touch screen an 8/10.
If the movement deadzone and sensitivity got fixed, it'd be a 10/10.
Now I'm sure I had more to write about but I've forgotten now. I'll edit it into the post if I can think of the other things.
Now as I said, I think the GSII is a smashing phone, sure there are a lot of niggles at the minute, but I know they'll get sorted soon. Just the points I've outlined in this thread are things I'm scared won't get sorted. But you never know, I'm really hoping they can get sorted/do get sorted.
As I said I've had 4 Galaxy S2's all had the above issues, and I've used 2 other S2's from friends who also have these issues, so it's widespread, I'm just curious if people actually notice it.
I've added a poll to the thread regarding these issues. Please don't lie to yourself about this stuff, if you notice it, please answer honestly

I honestly hadnt noticed any of this stuff, i even watched a video of the deadzone and couldnt replicate it myself. I also think the touch response is fine you must have a very light finger/thumb!
The ghosting i hadnt noticed probly because i dont read text as im scrolling i tend to go a page at a time and the fact that im too taken back with the smoothness that pages do scroll.
The blue tint you guessed it i hadnt noticed but then again its not often i hold my phone up to specially tuned monitors.. Then again maybe theres a reason for it maybe it helps reduce glare in sunlight, then again maybe im talking aload of ****e!
no offence but you sound like you could moan for england! chill out and focus on the things it does do well and you may notice the negatives less

Personally....I think your nuts. This is the best screen ever on a phone. I have none of those issues, the touch screen perfectly responsive, my whites are white as white can be. You keep getting your phone from the same supplier and that leads me to be what the problem is. mine is perfect in every way. lucky me I guess

Haha I could moan for england ;P
Nah it's just I'm very picky when it comes to screens. And I definitely expect the best on such a high end device, unfortunately the SGSII falls abit short on this.
It's still a great device. Really wish I didn't notice this sort of stuff haha.

Best screen on a phone possibly. It's not the best screen ever though, it's good don't get me wrong, but not the best.
And I assure you, your device has everything that I outlined in my original post, it's just down to the user if they notice it or not. When I used my friends Galaxy SII's (who both got it from different places to me and each other) I asked them about this stuff and they had no idea what I was on about, so I thought my phone was faulty and I had a look at their GSII's and theirs have the same problems aswell, they just don't notice them. (They did after I pointed it out though muwhahah)

I must not have a sgs2. Maybe its because mine is from first batch but I have none of your listed issues. After 4 devices, it cant be samsungs fault.

Heh, guys every SGSII have these issues, I'm not arguing that, was merely checking to see how many people notice these issues (not many in the grand scheme of things apparently) there's quite a lot of reports of these problems so it's just down to the user

I guess I have horrible standards. No shadowning on my phone.

The ghosting and blue-ish colortemperature I noticed right from the start. But to be honest: I really dont care. At least the ghosting is nothing which stands out of the crowd... all of them have it ... HTC, LG, Apple. The only reason you don't notice it as much, is the lower contrast on the other displays.
As for the sensitivity: It's a little lower than with my htc hd2, BUT I'm actually glad it is. The sensitivity on the HTC phones is ridiculously high. You don't even have to touch the screen and you end up clicking something, which can be quite annoying sometimes. On the SGS2 I never had any missclicks, nor did I have any non-responsivenesses. Perfect setup for my taste.

I think all of the average joe out there probably doesn't care about all this minor issues. You must have the intention to find the fault of the phone in order to get what you want to find but do you think most of us would be doing this? Haha.. Tbh I don't really care as long as the phone does what I want without falling apart. lol..

Yeah I was a bit surprised by the ghosting, having seen the response time claims, but neither that nor the colour temp (on 'movie') have really bothered me so far.
What has irked me a bit is the image sharpness. On a site like m.engadget.com the coloured text on white background has a dark outline all around it, which to me looks horrible. Anyone else noticed that?

I think the ghosting issue is due to the low fresh rate of the touch screen.It's lower than 60HZ.
When you scroll the screen,the animation is not smooth enough,so you see the ghosting.
It's more of a visual persistence issue.
I remember when some choppy animation showed in CRT,I can see ghosting.
Never the less,when your finger leave the touch screen,let it scrolling itself,you can see the "ghosting" would be less noticible.
But you can still see it,that's because of 60HZ refresh rate of the Display.
I just wondering if there is any way to change the fresh rate of the touch screen.

What are you doing that's causing ghosting issues? There is a definite color temp issue but that's how every amoled screen has been so far. I would take a little bit of blue tint over the black color performance

The thing that causes the ghosting, as I said in my original post, it fast movement. The screens pixels can't change fast enough so things leave a trail.
As I said the best way so see this is to loadup a long page with a white background and black text and then scroll down at a moderate pace, fast but not so fast you eyes your eyes canty follow the line of text. If toy do it right and you've got a decent set of eyes you'll see that the text leaves a trail.

Yep, there's a lot disappointments with the screen on this phone. However as the poll is so far proving, majority of people don't care for quality as much as us. Only a few others care/notice about the things we're complaining about.

Thanks .. Thats the funniest **** i have read all day...
Theres nothing wrong with my sgs2 and ive owned Hero's Desire's Nexus One's and even an LG2X.. This phone is superb.. This dude does sound a bit anal..

Hey. I can definately notice ghosting on this screen if i purposely try to but as others have said, it doesn't bother me in the slightest. When watching films or playing games it's non-existant.
As for the whites, you yourself stated you can't really notice until you hold the device against your professionally calibrated screen. How are the blacks in comparison? Out of interest, how much was that screen/calibration.
I think the main problem with alot of peoples gripes is focusing on only the weaker aspects of the phone rather than the device as a whole. People want perfection which unfortunately doesn't exist in the world of electrical consumer tech.

now i see this horrible grey everywhere i cannot even look at my phone any more!
I hope that this issue would be enough to change my device!

Hey drm111, as you know I have those problems too.
Did you have them on all your 4phones?
1) As you know I have this topic in wich one screen had this blue ish coat on the screen, noticable from the angles you talk abouth. But the other one does not have it.
So maybe not everyone has that blue coating? Did you investigated that further?
2) As you also know there is this yellowish/darker 1/3 of the left screen, probably some don't notice it. You have to be in a dark room or in a light one really looking for it. You read abouth this huh?
But I you didn't post it here. Aren't you having this problem? And did you have it on al of your 4 phones?
3) Ghosting, yes i notice it to. No sharp text when scrolling,is that the ghosting too?
I have this first generation ipod touch, text stays sharp when scrolling. Should be the case here too.
4) Than you have the grey tints, wich turn pink. You can see it in the topic of nongrata23. But some phone don't have it it seems. Software or hardware?
We need to figure out what is 'normal' and what isn't. As I don't want to send my phone back if it is normal at this point for all the gs2 that are on the market.

Let me start by saying i used to work for a PC magazine and was among those who blew the whistle on the nVidia texture replacement fiasco surrounding the Geforce 5800. I can see a single texture out of place in a high FPS game, so my eye is VERY keen.
The colour of the SGS2 is slightly blue yes, but mine is no worse than the average LCD, including the Retina display.
Response time is seemingly slower than the previous AMOLED screens ive seen, but again is more than a match for the LCDs out there.
I would say samsung have made a trade off between the sub pixel density and other factors. It works for me just fine.
The 16bit thing is interesting. It looks to me like the screen isnt 16bit, but it is using 16bit at times. Thats a driver issue.

Dim around the edges?

I did a search and haven't really seen anyone else report this.
My display seems dimmer around the edges. Does anyone else have this? It's not like a light bleed issue either.

Don't use the home screen to judge that if you are. Mine definitely dims by itself on the edges. Use the display tester app and see if you're getting the same results. I think I notice a very slight difference along the edge of the screen compared to dead center, but it's not enough to notice during normal use.

Thanks, I mainly notice it in crome on pages with whitespace and text. I'll check out the displaytester when I get home and see what I come up with.
Mine is also slight, but apparently enough to notice!
